Thread: powering wireless card

    Default powering wireless card

    Hi,

    I'm using openSUSE 11 on a new acer aspire 7720z with an atheros ar5007eg wireless card. The card is recognised by the OS, but I have no connection. Under windows xp, I can enable the card with a button seperate from the keyboard, but it won't work under linux. The bios settings doesn't have any option to enable/disable the device on boot. Is there anyway I can enable the card on booting into linux?

    I've tried both methods on the link you gave me and they both have problems. acerhk says that it's installed, but the when I go to start the module acerhk it's not there.

    With the acer_acpi, I get this error when I try to make:

    make -C /lib/modules/`uname -r`/build SUBDIRS=/home/mac/Desktop/acer_acpi-0.4 modules
    make[1]: Entering directory `/usr/src/linux-2.6.25.5-1.1-obj/i386/default'
    make -C /usr/src/linux-2.6.25.5-1.1 O=/usr/src/linux-2.6.25.5-1.1-obj/i386/default/. modules
    /usr/src/linux-2.6.25.5-1.1/scripts/Makefile.build:46: *** CFLAGS was changed in "/home/mac/Desktop/acer_acpi-0.4/Makefile". Fix it to use EXTRA_CFLAGS. Stop.
    make[3]: *** [_module_/home/mac/Desktop/acer_acpi-0.4] Error 2
    make[2]: *** [sub-make] Error 2
    make[1]: *** [all] Error 2
    make[1]: Leaving directory `/usr/src/linux-2.6.25.5-1.1-obj/i386/default'
    make: *** [acer_acpi.ko] Error 2


    any ideas?

    googling 'acerhk' and 'EXTRA_CFLAGS' yields:
    DamagedSpline's worst nightmare: acerhk compile fixed!
    [among others]

    But, you have another problem: You are NOT up-to-date on your patches...there
    have been TWO kernel updates since linux-2.6.25.5-1, so if you have
    (hard-wired) Intenet access, you should upgrade first (otherwise, you will
    just have to repeat the driver compile/build after the updates)

    Ok, I made the changes suggested by the link you gave me, but it still doesn't work. The documentation that came with acerhk says that there should be a folder in /proc/driver/acerhk, but it's not there.

    As for the kernel updates, I don't have a hard-line. Where can I download the updates?

    You can fix this problem by opening /home/mac/Desktop/acer_acpi-0.4/Makefile in
    an editor. In that file you will find a line that starts with CFLAGS+=... Change
    that to EXTRA_CFLAGS+=... to fix this error.

    I doubt that upgrading the kernel will make much difference.

    Sorry, I didn't make myself clear. I've made different changes to the Makefile. First by the line that starts with CFLAGS to EXTRA_CFLAGS and then by changing all references To CFLAGS. With either method I get no errors on make and make install, but it still doesn't work. The FAQ provided says there should be a folder called acerhk In the .proc.drivers but it's not there
